<p>PROBLEM TO BE SOLVED: To provide a portable information terminal device which automatically switches a report means to the one suitable for a public place while supply for an electric power to a transmission/reception means is cut off depending on public places. SOLUTION: Entering a sounding inhibited zone, a control part switches a report means from sounding to one other than that (306) based on a GPS information acquired from a GPS receiving part (301). When entering a sounding alarm region, the control unit controls a speaker to intermittently sound three times, alarming that a sounding inhibited zone is approached. When entering an electric-power supply inhibited zone, the control unit controls a power source to cut off supply of an electric power to the data transmission/reception part. Entering an electric power supply alarm zone, the control unit controls a light- emitting diode to slow down flickering speed for alarming.</p> |
